CHARLES OHINNOOK, OF BROOKLYN, NEW YORK.

IMPROVEMENT IN CORKSCREWS.

Specitication forming part of Letters Patent No. 40,674, dated November24, 1863.

To all whom it may concern'.-

Be it known that I, CHARLES CHINNOCK, of Brooklyn, in the county ofKings and State of New York, have invented a new and useful Improvementin Corkscrews, Giinlets, and Similar' Tools which are rotated in usingthem; and I do hereby declare that the following is a full, clear, andexact description ofthe same, reference being had to the accompanying`drawings, making a part ot' this specification, iu which- Figure 1 is alongitudinal central section of the tube or handle ot' my invention,shown in connection with a corkscrew, the device being adjusted readyfor use. Fig. 2 is a longitudinal central section of the tube or handlewith the corkscrew adjusted into it. Fig. 3 is a perspective view ot' myinvention, shown as a screw-driver, adjusted ready for use.

Similar letters otA reference indicate corresponding parts in thesevera-l figures.

The object ot' this invention` is to construct a corkscrew, gimlet,screw-driver, or other tool which is turned in using it in such. amanner that its handle will serve as a case to receive the tool when notin use and render the same capable of beingcarried in the pocket withoutany inconvenience, and at the same time be capable ot' beingmanufactured at a small cost and without having any of its partsdetachable.

To this end the invention consists in having the handle formed of a tubeand slotted longitudinally at two opposite points, said tube having aslide fitted within it, to which the shank of the tool is attached by ajoint, and all arranged in such a manner that the tool, When notrequired for use, may be shoved within the handle, and when required foruse drawn out from the handle and turned at right angles therewith, as4hereinafter fully set t'orth.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents a tube, which I design to construct ot' sheet metal,swa-ged into properform, closed at one end and open at the other, andhaving two longitudinal slots, a b, made in it at opposite points ot'its periphery, one slot, a', extending nearly the. whole length ofthetube,

ltrrminating a short distance from each end of It, and the other slot,b, extending from one end of the tube to a point a trifling distancebeyond its center, as shown clearly in Fig. 1. Within this tube Athereis fitted a slide, B, ot' cylindrical form, and having a pin, c, projecting from it, which passes through the slit a, and to one end of saidslide' the shank e ot' the corkscrew C or other tool is attached by ajoint, f. This joint admits of the corkscrew or other tool heiligadjusted in line with the slide B, as shown in red in Fig. 1, oradjusted at right angles with it, as shown in shaded blue tint. When thecorkscrew is turned or adjusted in linel with the slide B, the formermaybe shoved entirely within the case or tube A, as shown in Fig. 2, andby drawing out the corkscrew from the case or tube A until the pin cstrikes the edge of the slot a the corkscrew may be turned at rightangles with the slide, and the latter shoved back within the case ortube until the shank e strikes against the inner end ofthe slot b. Inthis adjustment of the corkscrew the latter is in a condition for use,the case or tube A serving as the handle. By this arrangement it will beseen that none ofthe parts require to be detached in adjusting the tool.They are all connected, and remain so in adjusting the tool Within itscase and in adjusting it for use at the outer side of the case.

The device may be carried in the pocket without any inconveniencewhatever, may be constructed at a moderate cost, and none of the partscan be mislaid or lost, as is frequently the case with similar deviceswhich are composed ot' detachable-parts.

My invention is applicable to various tdols, such as corkscrevs,gimlets, screw-drivers, tuningkeys for piano-fortes, &c. In fact, it isapplica-ble to all tools which are turned in using them. In Fig. 3 ascrew-driver, D, is shown attached to the slide.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The case or tube A, provided with the slots a b, in connection with theslide B, provided with a pin, c, tted in the slot a of the caso,

and the corkscrew C or other tool attached to the slide by a joint, f,substantially as herein set forth.
